my new project

True. Make sure you learn something when you dyno, that way if something happens on the street you can adjust your tune and save your car.

Or just get the wideband working and wired correctly and have the AEM do it on it's own.

If fuel pressure drops bad though, then no amount of adding fuel to the maps will make a difference. You could wire a fuel pressure sensor into the AEM also and have it adjust the fuel for small fuel pressure drops. Some factory ECUs actually do this. Some cars with factory fuel tanks and poor venting can go lean in the higher gears on a long run due to the fuel pressure dropping because vacuum builds up in the fuel tank and then the often already close to maxed fuel pump has to work a lot harder.

I would love to learn something while I'm there! but I hate when people sit and look over my shoulder when I'm working on their cars at work lol. So I usually just stay out of shanes way and let him do his thing unless he needs me to do something.

Good luck, hope you can get you goal!

Watch out for the liter bikes there can be a 10-20mph trap difference!

Thanks! I'm not too concerned with whether I win or lose. If I can hang with them I'll be happy. If I lose I lose :)

As for the wideband being wired in to the aem it supposedly already is. But I'm still waiting to get my new laptop. I'm not sure I trust the old fjo in the car anyway. I want to verify it's readings match up with what your dyno reads. If it does I will make sure to get it properly wired into the aem. If it doesn't then it will be replace and I will get the new one wired in properly.

I have been looking into fuel pressure gauges with a 5v reference and it seems that aem is the only one that makes one. so that is one of those is on my top priority of things to buy for the car.

Well there you go, already has a small failsafe.

What about one of the AEM failsafe wideband/boost gauges?

Indeed!

This would be a good Idea but I would want to use it to replace my current boost gauge and it looks as though the aem failsafe only reads to 30psi.

[4seasons69]

So I replaced the broken mounting bolt for my alternator today. When the bolt broke the spacer for the alternator relocation kit was lost so I made my own out of washers until I can order a new one from Jay racing. So the car is ready to go for Tuesday!

[goodhart]

You could just use the failsafe as a wideband and keep your current boost gauge.

[4seasons69]

I could but Idk if I could justify spending that much on a wideband that uses the bosch sensor unless I could use the boost gauge too

[goodhart]

The failsafe features alone would make it worth it, unless your ems can already do that of course.

I'm on not too familiar with aem so idk what kind of built in failsafes it has. I know Shane said it can adjust fueling based on afr and fuel psi inputs.
